moveTo method for Vector2

[MrOnlineCoder]

Hello. Very often in games there is need to move object A to object B smoothly. Can this function be implemented in SFML? Something like this:

pointA.moveTo(pointB, 1f);
//=> pointA is now closer to pointB by 1 pixel

It's not so common to move by one pixel. And your solution wastes CPU cycles because you recompute (pointB - pointA) for every pixel to move.

What is more common is to store a velocity and compute the move with the elapsed time.

pointA += velocity * elapsed.asSeconds();

1 pixel I used just for example

You can interpolate the two positions. To move a specific amount, you could multiply by a unit vector of the path.
